IMPROVED CAE-COUPLING.

To ALL WHOM rr MAY'GONCERN; y

Beit known that I, RANSOM IV. GREEN, of Bradford, in the county of'McKean, and State of Pennsylvania, have made a new and usefulimprovement in Car-Conpling; and I de hcreby declare Vthe following tobe a full, clear, and exact description of thenature, construction, andoperation of the same, sufficient to enable one skilled in the art towhich it appertains to Construct and use the same, reference being hadto the accompany# ing drawings, which are made part of thisspecification, and in which- Figur'e 1 is a horizontal section.

Figure 2 is a vertical section.

Figure 3 is a transverse section. i

The improvement consists in an arrangement in a flaring-moutheddraw-head of a shonlderedcoupling-pin in a gravitating frame, andpvotedspring-arm, for sustaining the pin previous to coupling.

In the drawings, A is the draw-head, with an opcnmouth, B. C C is arectangular frame, moving in ver:

tical grooves in the sides of the draw-head A. D is a coupling pin,having shoulders'EE. The pin is attached to the upper horizontalportionv of the gravitating frame, the key F being the means of securingthem in their connection. When the draw-heads are yet uncouplcd thelower end of the pin D rests upone shoulder, G, of the arm II, which `ispivoted by'a vertical axis, L, in a recess of the draw-head. The piutleL and arm H G arecast in one piece, and as they1 are journalled in theupper and lower edges of the draw-head,it`.bec0mcs necessary to providen means for introducing the parts into position. This is accomplished bymaking an opening in thefsde of the draw-head A, which is then closed bythe sliding-piece J, which keeps th'enxis L in position and closes theaperture. The link I, in the approaching draw-head, striking against thearm I-I, causes it to recede, and the pin D, being supported by theshoulder G, does not drop until the thickness of the` link .has passedfrom under; after which it falls so asV to engage the link, theshoulders E E resting upon it so as to maintain it in a horizontalposi-tion. The maintenance of this position is especially necessary inholding the linkready for coupling. The link may be withdrawn bylifting' the frame C; and the shouldered anni G H then assumes theposition shown in fig. 2,'being compelled thereto by the spring M on the`stud N, or by some other spring of suitable character and location. yThe axis L may be rotated as required by a wrench on the square K of thepintle. i

What I claim as new, and desire to secure by Letters Patent, is

The arrangement of the Haring draw-head B, the link I, the shoulderedpin E D, lguide-frame C, and the shouldered spring-arm'II G, operatingsubstantially as described.

To the above specification for an improved carcoupling I have signed myhand this first day of May, 1866.

RANSOM W. GREEN.
